(such as audio visual equipment, office-automation equipment, communications devices, electrical 
appliances and electronic toys).
Should you intend to use these products with equipment or devices which require an extremely high level 
of reliability and the malfunction of which would directly endanger human life (such as medical 
instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers 
and other safety devices), please be sure to consult with our sales representative in advance.
It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance 
of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow 
for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in 
order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM 
cannot be held responsible for any damages arising from the use of the products under conditions out of the 
range of the specifications or due to non-compliance with the NOTES specified in this catalog.
